About the Book

Turn Your AI Application into a Revenue-Generating Machine with the Ultimate Guide to SaaS Monetization.

Are you building the next great AI-powered SaaS, but struggling with the complexities of billing, subscriptions, and payments? In Volume 8 of the acclaimed AI with JavaScript & TypeScript series, author Edgar Milvus demystifies the art of monetization, providing a complete blueprint for building a scalable, secure, and intelligent revenue engine.

This is not just another book about Stripe. It’s a deep dive into the architecture of modern revenue systems, tailored for the unique challenges of usage-based and AI-driven products. Learn to move beyond simple monthly subscriptions and build a sophisticated system that handles everything from per-token billing and automated tax calculation to AI-powered customer support.

  • ✅ Stripe Integration Like a Pro: Go beyond the basics to master Stripe Checkout, Stripe Elements, the Customer Portal, and Stripe Connect for marketplaces.
  • ✅ Automated Revenue Recovery: Implement "Smart Dunning" workflows to automatically handle failed payments and drastically reduce involuntary churn.
  • ✅ Build an AI Support Agent: Create a fully functional, embedded AI chatbot using the Vercel AI SDK that can handle real-time billing inquiries, process refunds securely, and escalate issues.
  • ✅ Global Compliance Made Easy: Architect a system that handles multi-currency payments, automatic tax/VAT calculations with Stripe Tax, and adheres to GDPR data privacy standards.
  • ✅ Secure API Key Management: Learn to design and manage a secure API key system with environment scoping, role-based access, and automated rotation.
  • ✅ Capstone Project: Apply your knowledge to build an end-to-end, usage-based billing system from the ground up, combining event-driven architecture with a multi-agent AI workflow.
